Evaluation of hydrogen storage in sandstone reservoirs using H nuclear magnetic resonance spectroscopy.

Evaluation of the hydrogen storage capacity of porous rocks is crucial for underground hydrogen storage. Using H nuclear magnetic resonance (NMR) spectroscopy, we successfully characterized the hydrogen responses and identified storage mechanisms in Berea sandstone under varying water saturation. The results indicate that the injected hydrogen behaves as a free gas phase and is capable of occupying the empty pore volume regardless of the saturation state.

Novel Administration Routes, Delivery Vectors, and Application of Vaccines Based on Biotechnologies: A Review.

Traditional vaccines can be classified into inactivated vaccines, live attenuated vaccines, and subunit vaccines given orally or via intramuscular (IM) injection or subcutaneous (SC) injection for the prevention of infectious diseases. Recently, recombinant protein vaccines, DNA vaccines, mRNA vaccines, and multiple/alternative administering route vaccines (e.g.

RGS6 drives cardiomyocyte death following nucleolar stress by suppressing Nucleolin/miRNA-21.

Background: Prior evidence demonstrated that Regulator of G protein Signaling 6 (RGS6) translocates to the nucleolus in response to cytotoxic stress though the functional significance of this phenomenon remains unknown.

Methods: Utilizing in vivo gene manipulations in mice, primary murine cardiac cells, human cell lines and human patient samples we dissect the participation of a RGS6-nucleolin complex in chemotherapy-dependent cardiotoxicity.

Results: Here we demonstrate that RGS6 binds to a key nucleolar protein, Nucleolin, and controls its expression and activity in cardiomyocytes.

Experimental evaluation of cement integrity on exposure to supercritical CO using NMR: Application to geostorage.

Carbon sequestration is one approach to achieve carbon dioxide reduction in the atmosphere. Underground storage of CO requires an understanding of geochemical and geomechanical alteration on the integrity of the injection wellbore. In this study, we investigate the reactivity of supercritical CO (scCO) at 65 °C and 20.
